  • [SOLVED] Option Bytes Dialog

    For a project using STM32L011 we want to change BOOT0 behaviour by option bytes. As this is done only once and not frequently, we wont write and include any application code for this. For Ozone and J-flash project setup we can choose the controller with and without option bytes but we cannot find the dialogue to change the content therefore.Where can we find the dialogue in J-Flash or Ozone (or other tools?) to set the flags like Cube Programmer offers this with the option bytes panel dialogue?
  • Hi,
    The J-Link Tools do not provide a specific dialog for the ST device flags.
    The reason is that J-Link supports a wide range of devices (multiple thousand devices) and
    implementing this for all devices J-Link supports would simply be too much work.

    When selecting the device with option bytes enabled in J-Link, this simply means that you can write data directly to the option bytes (e.g. via J-Flash).
    So what you would have to do is:
    1) Add the optionbytes range to the file you are downloading with J-Flash.
    2) Fill the option bytes range with the desired valuse.
    3) Program the device.

    Best regards,
    Fabian
